2.2.2 The Heat Chart

The Heat Chart is on the right side of the
Monitor page and shows the status of
critical rules. Monitored servers are organized by groups. To
view the status of a specific server, click the
+ button next to the appropriate server
group.

Whenever a new agent contacts the Service Manager for the first
time, all the rules in the Heat Chart Advisor are automatically
activated. These Advisors monitor the status of the server and
agent, critical operating system indicators, and important
events related to your MySQL servers. An example follows.

The status unknown typically applies when an
agent is down and can no longer report the status of the server
that it is monitoring. The status unknown can
also apply if the data that should be collected is not available
on the server being monitored.

You can open the Heat Chart in its own browser window by
clicking the Standalone Heat Chart link
immediately below the Heat Chart on the
left. You can set the refresh rate to a different rate than the
setting on the Monitor page.

In addition to showing the most important advisors, the
Heat Chart also has columns that display
the number of critical, warning, and informational alarms.
Clicking the hyperlink in any one of these columns takes you to
the Events tab, which gives more detailed
information. For more information about events, see
Section 2.4, “The Events Tab”. Hovering over the heat chart also
provides server counts within the tooltips pop-up.
